Apparatus for displaying image by using residual image effect

ABSTRACT

Disclosed relates to an apparatus for providing moving or still images to a passenger in a moving train through a plurality of monitors established in a railway tunnel by using a residual image effect. The apparatus of the invention comprises a main server including image data, such as moving or still images, a controller, connected to the main server through a dedicated network or Internet, for controlling the image data transmitted from the main server, and a plurality of monitors, installed at predetermined intervals in a tunnel, for receiving the image data from the controller and displaying the moving or still image.

TECHNICAL FIELD

[0001] The present invention relates to an apparatus for displayingimages by using a residual image effect and, more particularly, to anapparatus for providing moving or still images to a passenger in arunning train through a plurality of monitors established in a railwaytunnel by using the residual image effect. A main server of theapparatus supplies image data to the plural monitors by way of adedicated network or Internet.

BACKGROUND ART

[0002] In general, the inside of the tunnel, through which automobiles,or railway trains travel, is kept relatively darker than the other busstops or railway stations. Besides, the inside of the tunnel is noteasily used for any advertisement medium, whereas various advertisingmeans, such as pictures, outdoor billboards or electric signboards, areestablished in the railway station and the bus stops. That is, theinside of the tunnel is a useless space, except for its peculiarfunction for providing a traveling space of the vehicles.

DISCLOSURE OF INVENTION

[0003] Accordingly, the present invention is made to provide anapparatus for displaying moving or still images to a passenger in arunning train through a plurality of monitors established in a railwaytunnel, using a residual image effect.

[0004] To accomplish of the invention, the apparatus for displayingimages by using residual image effect comprises a main server includingimage data, such as moving or still images; a controller, connected tothe main server through a dedicated network or Internet, for controllingthe image data transmitted from the main server; and a plurality ofmonitors, installed at predetermined intervals in a tunnel, forreceiving the image data from the controller and displaying the movingor still images.

[0005] It is to be understood that both the foregoing generaldescription and the following detailed description are exemplary andexplanatory and are intended to provide further explanation of theinvention as claimed.

BRIEF DESCRIPTION OF DRAWINGS

[0006]FIG. 1 is an outline showing how an apparatus for displayingimages by using a residual image effect in accordance with the presentinvention is established in a tunnel; and

[0007]FIG. 2 shows how divided images stored in a controller aresupplied to a plurality of monitors.

BEST MODE FOR CARRYING OUT THE INVENTION

[0008] Referring to FIG. 1, the apparatus for displaying image by usingresidual image effect in accordance with the present invention includesa plurality of monitors (11 ₁-11 _(n)) installed at regular intervals inthe tunnel. Each of the monitors (11 ₁-11 _(n)), connected to acontroller (15) by means of dedicated lines (13 ₁-13 _(n)), receivesimage data. The monitor (11) is made of a CRT monitor, an LCD monitor,or an LED monitor.

[0009] Besides, the apparatus for displaying image using residual imageeffect includes a sensor (17), established in the tunnel, for detectingthe speed of running vehicles. The sensor (17) is coupled to thecontroller (15) and transmits the detected speed.

[0010] Meanwhile, according to a preferred embodiment of the invention,the controller (15) is interfaced with the running vehicle by radio andreceives the speed covered. That is, the controller (15) providesdivided image data to each of the monitors (11 ₁-11 _(n)) according tothe covering speed received from the vehicle.

[0011] The controller (15) is connected with a main server (10)including image data such as moving or still images by way of adedicated network (A) or Internet. The main server (10) has an inputmeans for inputting image data, a storing means for storing the imagedata input from the input means and a transmitting means fortransmitting the image data to the controller (15).

[0012] Meanwhile, according to a preferred embodiment of the invention,the image data input to the main server (10) are divided atpredetermined periods according to the covering speed of vehicle. Thedivided image data are sent to the plural monitors (11 ₁-11 _(n))through the dedicated lines (13 ₁-13 _(n)). Accordingly, when a subwaytrain (1), for example, goes into the tunnel, the traveling speed of thevehicle, detected by the sensor (17) or transmitted from the vehicle, isreceived to the controller (15). Then, the controller (15) forwards aplural number of divided images corresponding to a specific image data,for example, n-divided image, to each of the monitors (11 ₁-11 _(n))through the dedicated lines (13 ₁-13 _(n)). That is, first divided imageis supplied to first monitor (11 ₁) through first dedicated line (13 ₁);second divided image is provided to second monitor (11 ₂) through seconddedicated line (13 ₂); n⁻¹ divided image is sent to n⁻¹ monitor (11_(n−1)) through n⁻¹ dedicated line (13 _(n−1)); and n divided image isforwarded to n monitor (11 _(n)) through n dedicated line (13 _(n)),such that the specific moving image can be viewed by the passenger inthe covering train.

[0013] The divided moving images displayed on each of the monitors (11₁-11 _(n)) create a residual image effect on the passenger in thetraveling train (1). That is, the passenger can obtain variousinformation through the moving or still images displayed on the monitors(11 ₁-11 _(n)) according as the train penetrates in the tunnel.

[0014] Meanwhile, each of the monitors (11 ₁-11 _(n)) is spaced away atpredetermined intervals so that the passenger of the train (1) canrecognize is the divided moving image by the residual image effect. Thatis, the passenger giving a glance at the first divided image on thefirst monitor (11 ₁) meets the second divided image on the secondmonitor (11 ₂) adjacent to the first monitor (11 ₁) before the residualimage of the first divided image disappears, such that the passenger canrecognize the first and second divided images consecutively.Accordingly, the process of recognition is made in consecutive ordertill the passenger recognizes the n divided image displayed on the nmonitor (11 _(n)) such that the passenger appreciates moving or stillimages in the train penetrating into the tunnel.

[0015] Industrial Applicability

[0016] The apparatus for displaying image by using residual image effectin accordance with the invention provides moving or still images to thepassenger in the vehicle through the plural monitors established in thetunnel.
